Which hormone/vitamin am I thinking of? Relates to hair growth in new places

I remember reading that the reason you begin growing hair in new places once you pass a certain age (Developing back hair in middle age, for instance) relates to a certain vitamin or hormone that your body naturally produces -- this substance inhibits hair growth, and your body naturally tends to produce less as you age, allowing hair to grow in additional places. I vaguely recall this being lycopene, but I don't know if I'm remembering that accurately because it's not showing up in a google search. Anyone able to tell me what substance it is that I'm remembering reading about?
